0.10.4 is Atmosphère's twenty-seventh official release. fusee-primary was last updated in: 0.10.4. With thanks to the @switchbrew team, Atmosphère 0.10.4 is bundled with hbl 2.3, and hbmenu 3.2.0. The following was changed since the last release: With major thanks to @Adubbz for his work, the NCM system module has now been re-implemented. This was a major stepping stone towards the goal of having implementations of everything in the Switch's package1/package2 firmware. This also lays the groundwork for libstratosphere providing bindings for changing the installed version of the Switch's OS. Please Note: The NCM implementation will initially be opt-in. The Atmosphere team is confident in our NCM implementation (and we have tested it on every firmware version). That said, this is our first system module that manages NAND savegames -- and caution is a habit. We do not anticipate any issues that didn't come up in testing, so this is just our being particularly careful. Users interested in opting in to using our implementation should set stratosphere!ncm_enabled = 1 in BCT.ini. In the unlikely event that any issues are encountered, please report them to @SciresM. The NCM implementation will stop being opt-in in a future update, after thorough testing has been done in practice. A bug was fixed in emummc that caused Nintendo path to be corrupted on 1.0.0. This manifested as the emummc folder being created inside the virtual NAND instead of the SD card. It's unlikely there are any negative consequences to this in practice. If you want to be truly sure, you can re-clone sysmmc before updating a 1.0.0 emummc to latest firmware. Stratosphere system modules now use new Nintendo-style FS bindings instead of stdio. This saves a modest amount of memory due to leaner code, and greatly increases the accuracy of several components. These bindings will make it easier for other system modules using libstratosphere to interact with the filesystem. This also lays the groundwork for changes necessary to support per-emummc Atmosphere folders in a future update. Atmosphere's fatal error context now dumps 0x100 of TLS. This will make it much easier to fix bugs when an error report is dumped for whatever caused the crash. General system stability improvements to enhance the user's experience.
